PUNCTURE-PROOF TIRE.

To all whom z'may concern:

Be it known that I, HUGH A. FALVEY, citizen of the United States of America, and a. 'resident of Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Puncture-Proof Iires, of which the following is a specification,

This invention relates to thatclass of armored pneumatic tires in which a plurality of small sections or plates of puncture resisting material are arranged 1n overlapping series on and between pliable sheets of woven fabric or like mater1al to provide a puncture resisting lining or insertion for the casing of the tire, and has for its object:-

lTo provide a simple andrefiicien; structural association of the aforesaid overlapping puncture resisting sections or plate -in relation to each other and to their pliable carrying and inclosing webs of fabric to constitute a puncture resisting lining or insertion for the tire casing, and in which free local and independent movement between individual sections or plates can" take place, uent avoidance of the ordinary curling up o the margins of the sections or plates and the bending Vthereof in actual use, all as will hereinafterl more fully appear.

In the accompanying drawings Figure l, is a detail transverse section of a pneumatic tire having the present im as a puncture resisting l1n1ng. j

Fig. 2, is a detail plan view ofthe liner or insertion in an unfolded. condition, and with portions of the plurality of webs and of the overlapping series of puncture resisting sections or plates removed, to illustrate the relative arrangement of said parts.

Fig. 3, is a detail longitudinal section on Like reference numerals parts in the several views.

Referring to the. drawing, 1 designates the outer` casing of a pneumatic tire, and 2 indica@ like the inner air holding tube usually associated therewith.

lining whichl in 'the preferred formof the present invention shown in Fig. lis disposed loosely between the tirecasing l and the inner tube 2, the lscope ofthe present invention-embracing the use of the present structure as an insertion in the annular crown portion of the casing 1v as usual in Specification of Letters Patent.

plates or sections 8 and 9 ing Patented Dec. 2, 1919.

many of `the armored tires shown in the 4;, 5 6 Iand 7 designate a plurality of sheets or webs of Woven fabric or likepliable material arranged in superimposed relation and preferably attached together at' their'margins or edges by cement or other usual fastening means, with their main portions free from attachment and in loose association so as to be capable of limited independent movement in relation to each other. In the preferred formv of the present invention shown in Figs. 2 and 3 the two. central sheets or webs 5, 6 constitute the attaching bases for the plurality vof overlapping puncture resisting sections or plates 8 and 9 hereinafter described, with the outer and inner webs 4 and 7 constituting coverings for said plurality of plates or sections.

he puncture resisting sections or plates 8 and 9 aforesaid, are preferably square as with fastening clips, which they are secured ing sheets or webs, 5, 6. struction eachplate of shown, and provided or prongs 8', 9 by to the central carryoverlap an end of the next adjacent plate in the circumferen-` tial arrangement of the same in the tirecasing, and such overlapping ends are provided with lrounded projections or flanges 10, formfriction reducing bearings between the 'overlapping portions of such plates.

In the particular circumferential arrangement of the puncture resisting sections or plates shown in Figs. 2 and 3, one end of each individual. section 'or plate'of one plurality, overlaps the end of one adjacent section. or plate and underlies the end of the other adjacent section or plate of said plurality, and

wlth such arrangement it only requires the provision of a flange or rounded projection 10 upon one ofthe engaging ends of two adjacent sections or plates.

1l designate fillings of elastic material arranged in and vvbetween the plurality of overlapping sections or plates 8, 9 and of the adjacent sheets or webs 4 and 7 a carrying out, ofthe present invention; they of any desired shape,`

In the present coneach plurality of roo . adapted to provide an even bearing surface 3 designates an annular puncture resisting fillings l1 may be of vulcanizable'material, l.

which after application in the manner above stated is vulcanized in place in any ordinary manner.

Having thus fully described my said in,-

vention what I claim as new and desire to of superimposed sheets of pliable material, secure by Letters Patent, is and outer and inner pluralites of puncture l. Apuncture resisting lining or insertion resisting plates carried by said sheets in for pneumatic tires comprising, a plurality transversely spaced relation With the plates 20 of superimposed sheets of pliable material, of one plurality overlying the spacing of the and outer and inner pluralities of puncture other plurality, the plates of each plurality resisting plates carried by said sheets in having oblique relation to each other with transversely spaced relation With the plates an end of each plate overlapping a next adof one plurality overlying the spacing of the jacent plate and with the other end under- 25 1o other plurality, the individual plates ofeach lying an end of another adjacent plate, and

plurality overlapping each other with adwith said adjacent ends 1n sliding contact jacent ends in sliding contact and provided and provided Vwith bearing projections' or with bearing projections or anges, substanflanges, substantially as set forth.
